VERY good info. About to do a LS swap on a 89 Mustang and definitely want to keep the AC. This info should definitely help. Thanks for the write up!! Did you happen to make a diagram of your actual harness? Or take any pictures? Thanks again!

the schematic is posted on the first page, its just a little jumper harness with @ 6 wires and a relay.

The Holley mount looks really nice and can't beat the price. Anyone have pictures of the SD7 installed? What pulley offset does it use? Corvette?

Attached is a picture and link to one i've made. The down side is it uses the truck offset and modified F-body waterpump. The compressor tensioner setup has been installed in my 72 Malibu for a year now and has been great.

seting one up now with a sanden compressor , i think that is a diferant bracket pictured with the pancake compressor , i had one of those compressors once bought with a gm accesory drive for a sbc , they suck some horsepower and put alot more drag on the engine than a sanden unit , had to use a stepup throttle selinoid with it , or it would kill my smallblock with a big cam , will post pics when done went with the complete holley system as old ( a bodies) have issues with steering box clearance going on an 08 ly6 and into a 64 chevelle with power stearing

Where did you mount the 3-wire pressure sensor that the pcm has to see in order to kick the compressor on? Is there a port on the high side line?

welded it in the high side line, basically cut the factory g-body line in 1/2 and sectioned in a piece of the f-body line that had the pressure switch

I love it!
I'm wanting to retai the factory a/c compressor ( still charged just laying to the side lol) on my '94 z71, and that Holley bracket makes it look MUCH easier to obtain.
Now... Just gotta see If they sell one with the truck bracket offset or if I'll just have to make spacers...

They have different spacers for the corvette, f-body and truck accessories - check the Holley site

Did you ever have trouble not having the diode? Did anyone try installing it the other way around like mentioned?

lt4malibu

iTrader: (39)

i put it in the other way and it worked great, guy who bought the car off me never had a problem with it either. i would definately use the diode otherwise it could backfeed.

Okay thanks for the update. Cannot believe GM screwed up the schematic... Oh wait. Yes I can. Although very obvious if you know what you're looking at I suppose.

I work on these things all day every day and I didn't even notice it (till it popped the fuse lol)

I'm having trouble getting the factory 87' Cutlass AC line installed on this set-up. I have the BRP mounts and wonder why I can't get it to line up to install? Errr. It's so bad that I am wondering if I have to chop this new 87' line apart in order to have customized lines made to work. I'm wondering if you had to ben yours to get it to line up to fit???
Any help would be greatly appreciated!
Thanks!

yes I did bend them slightly, but which line are you talking about?
